How Installing UV Lights in Your HVAC System Kills Viruses

The sun releases three types of ultraviolet (UV) light: UVA, UVB and UVC. You are likely most familiar with UVA and UVB rays, which may result in sunburn unless you use a broad-spectrum sunscreen. UVC rays are separate. The sun still creates them, but the earth’s ozone layer absorbs all UVC rays, so you aren’t exposed to them in nature. 

UVC light comes with outstanding germicidal benefits. In actuality, it has been used as a cleaning method for decades. As the highest energy portion of the UV radiation spectrum, UVC light helps break down microorganisms including bacteria, algae and fungi within 10 seconds of contact. When installed in your HVAC system, germicidal UV lights could dramatically boost your indoor air quality

How Do HVAC UV Lights Work? 

Ultraviolet lamps are installed within your ductwork, where they function constantly. Air flows past the lights when the furnace or air conditioner operates, and powerful UVC rays inactivate and neutralize most viruses, bacteria or mold present in the air. Inactivated microorganisms won’t reproduce and die shortly after UVC exposure. 

5 Advantages of Installing UV Lights in Your HVAC System 

With other types of air cleaning available, why should you consider installing a UV light in your HVAC system? Consider these benefits: 

1. Clean Coils 

The evaporator coil in your HVAC system is frequently wet, particularly in the summer. By continuously shining UVC light on the coil, mold and bacteria cannot grow. 

2. Healthier Indoor Air 

Media air filters can latch onto minuscule bacteria and viruses. UV lights lower the concentration of microorganisms in the air without reducing airflow. 

3. Enhanced Efficiency 

By providing enough airflow and keeping the equipment clean, UV lights help your HVAC system work more easily. This, in turn, reduces your energy costs every month. 

4. Longer HVAC Life Expectancy 

Clean equipment performs more steadily and needs repairs less regularly. It can even work years longer. 

5. Less Chance of Condensate Drain Line Clogs 

Air conditioners and high-efficiency furnaces create condensate, which drains away into a nearby pipe. Over time, algae can clog the drain line. By preventing organic growth in the first place, UVC lights lower the chance of water damage from a blocked condensate drain pan. 

Who Should Install Germicidal UV Lights? 

When you review all the benefits they offer your HVAC system, UV lights could quickly prove useful in any home. You are most likely to appreciate installing HVAC UV lights if you or anyone in your home has: 

  • Allergies 
  • Asthma 
  • Any respiratory condition 
  • Weakened immune system 

If you’re looking into adding germicidal UV lights, talk with Service Experts Heating, Air Conditioning & Plumbing. We can recommend the perfect system based on your HVAC equipment and indoor air quality needs. It’s best to leave UV light installation and maintenance to an expert since UVC exposure could lead to skin or eye injuries.
